Car Key Cutting Explained

Cutting keys for cars is more than just bending metal. It is a complex process that ensures safety, functionality and long-term use of keys.

It is not unusual to lose your car keys or have it break off in the lock. To ensure you're able to always drive your vehicle you'll need to have a replacement key cut.

Transponder Keys

If your car was manufactured in the last 20 years, it is likely that it has a transponder chip. These microchips are located in the key's handle and send a signal to your vehicle's onboard computers when you turn the key. The computer onboard is able to verify the digital serial number of the chip prior to allowing the car to start. This prevents car thieves from taking over your vehicle because they'd have to be aware of the unique serial number.

The microchip in your car key transmits a low-level radio signal to the receiver inside the car. The radio signal activates the microchip, which transmits a code to the car's onboard computer. The car will only begin if it recognizes this code. This stops "hot wiring" or other methods of stealing cars.

Locksmiths that offer these services can create car keys with chips. Some auto dealers like AutoZone offer them. They have a vast variety of keys and can assist you in choosing the appropriate one for your car. They can assist you in programming your vehicle's chip which is needed to use the device.

The VATS (vehicle-anti-theft system) key is another type of key that is difficult to duplicate. They have a resistor that is black on the blade of the key. It can be programmed to one of fifteen possible values to prevent it from starting a car that's not designed to. These keys are expensive and require an instrument for programming keys, which is only available at a few locksmiths.

VATS Keys

Before transponder keys and vehicles with computer chips that control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). VATS uses a key with a resistor embedded in it to ensure that the correct key was used to start the car. The VATS pellet that is black that is located in the middle of the VATS Key isn't an electronic chip that is like those present on modern keys. It is simply a block or carbon that is sized to have an electrical resistance.

GM used 15 different resistances for the VATS Pellets. They connected them to key blades in a way that, when the key is turned in the ignition a coded message is sent to the module. If the signal matches the resistance value of the transistor in the VATS pellet the relay in the starter circuit is activated and the engine will start to run. This does not make a car safe from burglary however, it can deter thieves for at least fifteen to twenty minutes.

Unfortunately, after a lot of use the VATS module in your car may start to wear out. The two wires that connect the ignition are moved each when the key is inserted. Over time the wires could begin to break. When enough wires break the signal to the module is lost and the module won't be able to start the car.

The good news is that you can solve this issue at home by decoding your own VATS key. You'll require a multimeter and an indicator chart to determine the resistance value of your key, but it is not difficult at all. You can determine the resistance value by putting one of the leads on the prongs of metal on both sides of your key.

This is a great way to test a brand new key and see whether it works in your car. Just be sure to remove the key from the ignition prior to testing it, or else the new key could have an incorrect VATS value and may not function in your car.
